I was sceptical about the poll you had going in the tactics section on this, found it all a little bad taste considering the wait that was going on but credit where credits due that is a fabulous OP and I have to say I am intrigued.
The Brazil tactic you had was brilliant, results wise, but didn't really suit me and my tendency to use wingers. However, this does.
What I am going to do is something a little Southampton esque. I am going to start a new game with this with Wolves in League One who yes, are a lower league side but what is good about them is they have a great squad for that league, good resources, good stadium and training ground and most importantly good Youth Academy. I am going to use that as an opportunity to hone a "philosophy" all throughout the club using this system and I am optimistic.
I will report back as and when.
EDIT: I know you state during testing this did not work with "weaker" sides, however, I think your being a little harsh on yourself/those sides as you also stated this was tested with there original squads. Clearly the intention of using this tactic with my Wolves team is to improve the side gradually season on season to the point in which hopefully they will not be considered a "weak" side.
